Job description

About the Role

We are seeking a data-driven Senior Information Architect (App & Web) to join our company. You will shape how hundreds of thousands of daily users discover, navigate, and complete tasks across our iOS, Android, and Web platforms. This is a hands-on role focused on systematically auditing existing products, designing resilient end-to-end user journeys, and predicting edge cases in high-traffic scenarios.

Key Responsibilities

1. Core Information Architecture & System Structuring

• Sitemaps & Global Navigation Patterns: Define, optimize, and maintain comprehensive sitemaps and global/local navigation frameworks for mobile apps (iOS/Android) and responsive web applications.

• Content Audits & Inventories: Conduct systematic content inventories and audits across existing digital touchpoints to evaluate structural health, drop-off points, and taxonomy effectiveness.

• Taxonomy & Controlled Vocabularies: Develop, document, and standardize multi-level content taxonomies, tagging systems, and controlled vocabularies to support robust searchability and filtering.

• Labelling Systems & Microcopy Clarity: Design intuitive labeling systems and UI microcopy hierarchies that clarify navigation paths and reduce user cognitive overhead across complex workflows.

• End-to-End User Flow Architecture: Map detailed user journey flows, task flows, and decision trees covering key customer scenarios from discovery to task completion.

• Cross-Platform Navigation Continuity: Ensure seamless structural alignment, deep-linking schema, and smooth transitions between web user acquisition funnels and mobile app retention loops.

2. Risk Prediction & Edge Case Engineering

• Heuristic Audits & Usability Friction Identification: Routinely audit current production apps and web pages to detect findability gaps, structural bottlenecks, and unnecessary navigation friction.

• High-Concurrency Edge Case Modeling: Map failure modes and structural edge cases during peak concurrency scenarios (e.g., flash coupon claims, queue timeouts, weak connectivity, and booking clashes).

• Fallback Pathways & Error Recovery: Design resilient error-handling states, fallback navigation paths, and recovery loops to protect conversion rates and user trust during system latency or transaction errors.

• System Architecture & Scale Alignment: Anticipate structural scaling constraints to ensure taxonomies and sitemaps accommodate future feature releases, product line expansions, and content growth.

3. Data-Informed Iteration & Validation

• Data-Informed Architectural Iteration: Utilize quantitative product analytics (Mixpanel, Amplitude, Google Analytics) and qualitative research to validate IA updates against core business KPIs.

• Design System & Governance Collaboration: Partner with Design System maintainers and Product/Engineering leads to establish and govern global IA patterns and structural UI guidelines across teams.

4. Cross-Functional Alignment

- Translate complex business logic and research insights into clear structural wireframes, journey maps, and IA documentation.

- Collaborate closely with Product Managers, UX/UI Designers, and Engineering leads to find optimal trade-offs between UX excellence and technical feasibility under legacy system constraints.

Requirements

- Proven experience as an Information Architect, UX Designer with strong IA focus, or similar role, ideally on consumer or B2C mobile apps and web products.

- Strong portfolio demonstrating user journey design, sitemaps, flow diagrams, navigation systems, and content organisation work.

- Solid understanding of mobile app information architecture principles and differences between app and web patterns.

- Experience creating and facilitating user flows, journey maps, and structural wireframes.

- Ability to balance user needs, business goals, and technical constraints.

- Comfort working with analytics tools and research insights to measure and improve IA decisions against KPIs.

- Demonstrated ability to work within established design standards and uphold company core values in day-to-day decisions.

- Excellent communication and documentation skills; comfortable presenting IA recommendations to cross-functional stakeholders.

- Familiarity with common tools such as Figma, Miro, FigJam, Whimsical, or equivalent for flows, sitemaps, and collaboration.

Preferred Qualifications

- Experience in mobile-first or app-heavy product companies.

- Hands-on experience with funnel analytics platforms (Google Analytics, Mixpanel, Amplitude, etc.) and translating data into IA recommendations.

- Background in content strategy, taxonomy design, or service design.

- Understanding of accessibility and inclusive design principles applied to navigation and information structure.

- Exposure to A/B testing or analytics-informed IA iteration.

- Degree or equivalent experience in Human-Computer Interaction, Interaction Design, Library/Information Science, or related field.
